I don't entirely understand what you mean by external link but if the problem is because the quiz is opened in a frame then you can either set the link to open the quiz in a new window or even a modal dialog or set the link to open a web page which redirects the top window to the quiz. You can also add a link in the quiz description that returns to the opening page.

If your concern is that the quiz will be visible on the main page then you can always put it in a topic which is not displayed. So for instance if you use in the course 10 topics, you can put the quiz in topic 11 and since topic 11 is not displayed students won't be able to see the quiz nor access it from the main page. Of course the quiz will still be accessible from other places such as the activity report or the quizzes page so I don't know if that will be of much help unless you disable these other places.

Yes, I thought about that too but since I don't have access to the css I tried setting the padding and margin of the img to 0 which worked on another environment but not on Moodle. By the way the editor indeed doesn't seem to be the problem because it displays the images properly and the gap appears only when the images are displayed on the page.

Well, element's dimensions in HTML usually don't force anything on the content of the element. But that gap between the images is really irritating. I don't know why the images are rendered that way despite their settings and I'll try to find out. There might be a simple explanation for that.
The obvious quick workaround is to make one image from the two but that might not be very effective if there are lots of other parts where these two come from. Absolute positioning may also solve the problem but that's a pain. So we'll have to look for something else.

So I guess it's a bug and if not in the tracker already I will add it.
